Disclaimer
Last updated: June 30, 2026
1. Tools Provided "As Is"
All tools on QingChuan Toolbox are provided "as is" for your convenience. We do not make any warranties — express or implied — about the accuracy, reliability, or fitness of these tools for any particular purpose.
Browser-based tools have inherent technical limitations. Image processing in a browser tab cannot match the precision or capability of dedicated desktop software like Photoshop or GIMP. Calculation tools provide estimates that should be independently verified before making decisions based on them. AI-powered generators produce suggestions that need human review before publication.
By using any tool on this site, you acknowledge that results may vary depending on your browser, device, operating system, and input data. We recommend testing output before relying on it for critical work.
2. No Professional Advice
The financial calculators on this site — including the ROAS calculator, payment fee calculator, and money-related tools — provide estimates for informational purposes only. They are not a substitute for professional accounting, financial planning, or investment advice.
The health calculators (BMI, calorie estimators, etc.) use standard formulas but cannot account for individual medical conditions, medications, or other factors that affect health metrics. Consult a qualified healthcare professional before making decisions based on these calculations.
No tool on QingChuan Toolbox constitutes legal, medical, financial, or any other form of professional advice. If you need advice, hire a professional — don't rely on a browser-based calculator.
3. Tool-Specific Limitations
Image tools (Watermark Remover, Background Remover, Image Resizer, Compressor): All image processing happens locally in your browser using the Canvas API. Your files are never uploaded to any server. However, browser-based processing produces different results than desktop software — colors may shift slightly in CMYK-to-RGB conversion, compression artifacts may appear at aggressive settings, and AI-based removal (inpainting) may leave visible traces on complex backgrounds. For professional or commercial use, verify output quality on the intended medium (print, web, etc.) before publishing.
AI content generators (Hook, Script, Bio, Ad Copy, Product Description, Email Subject, Landing Headline): Our generators use template-based pattern matching — not external AI APIs like GPT or Claude. This means your inputs never leave your browser, and generation is instant and free. However, the output is limited to the patterns and frameworks programmed into each tool. The generated content represents starting points based on proven marketing formulas — you are responsible for reviewing, editing, and adapting all output before publishing. We make no guarantees about conversion rates, engagement, or any other performance metric.
Calculators (ROAS, Payment Fees, Content ROI, A/B Test, Health): All calculations use standard industry formulas but cannot account for edge cases, regional variations in tax law, or platform-specific fee structures that change over time. Always double-check important calculations against official sources.
Generators (QR Code, Password, Palette, Schema Markup, UTM): These tools produce output based on your inputs and standard specifications. QR codes follow ISO/IEC 18004 standards, passwords use cryptographically secure random generation, and UTM parameters follow Google Analytics conventions — but verify output before use in production environments.
4. No Data Responsibility
Since all processing happens locally on your device and no data is transmitted to our servers, we cannot recover, access, or be held responsible for any data or files you process through our tools. You are solely responsible for maintaining backups of your original files before processing. If a tool produces an unexpected result, your original file remains untouched on your device — the tool reads it, processes a copy in memory, and outputs the result without modifying the source.
5. Affiliate Disclosure
QingChuan Toolbox may participate in affiliate marketing programs. This means some links on this site may earn a commission if you click through and make a purchase — at no additional cost to you. Affiliate relationships do not influence which tools we build, how we rank them, or what we recommend. Our tool selection is driven entirely by user needs and our own assessment of what's useful.
We currently participate in programs through the Awin affiliate network (Publisher ID: 2914147). When a link is an affiliate link, it is marked with rel="sponsored" for transparency and search engine compliance.
6. Third-Party Links
This site contains links to external websites and services that are not operated by us. We have no control over, and assume no responsibility for, the content, privacy policies, or practices of any third-party sites. We recommend reviewing the privacy policy and terms of every site you visit.
7. Availability and Uptime
We strive to keep QingChuan Toolbox available 24/7, but we do not guarantee uninterrupted access. The site may be temporarily unavailable due to hosting maintenance, browser compatibility issues, or factors beyond our control. Since all tools are client-side, any tool you've loaded will continue to work even if connectivity is interrupted mid-session — though you won't be able to navigate to new pages.
8. Changes to This Disclaimer
We may update this disclaimer as we add new tools or as the legal landscape evolves. The date at the top indicates the last revision. Continued use of the site after changes constitutes acceptance of the updated disclaimer.
9. Contact
